DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the figures, there is disclosed a service trailer 10. Service trailer 10 may include trailer 12; fresh water tank 14; grey water tank 16; generator 18; light 20; pump 22; water hose and connector 24; pressurized accumulator tank with diaphragm 26; water outlet line 28; water outlet 30; grey water intake line 32; grey water intake pump 34; grey water macerator 36; and grey water outlet 38. Each of these components are shown in the drawings and will be discussed in further detail hereafter.

Trailer 12 may be a sixteen foot double axle department of transportation approved trailer. The trailer in a preferred embodiment is a flatbed trailer. The trailer includes a hitch 50 for mounting to a truck or other vehicle for pulling the trailer. Once to the site of use, the trailer is removed from the source of transportation. The trailer may include jack stands 52 which are rotatably held in a horizontal non-use position when the trailer is in transport and when in use rotated to a vertical position to stabilize the trailer as shown in FIGS. 1 and 3.

As seen in the drawing, the trailer 12 includes a fresh water tank 14, preferably a 750 gallon fresh water tank. It includes a fresh water intake hatch 40, as shown for example in FIGS. 2 and 3, for receiving fresh water and drainage port 41 at the bottom thereof. There is also a water removal port 43 as discussed below. Tank 14 is secured to the trailer by straps 42 or other means. There is also a similar grey water tank 16 having a hatch 40, also secured by straps 42, and having a drainage port 41.

There is a generator 18, preferably a diesel powered generator. A preferred generator is a Magnum generator and includes a pole light 20. As shown in the figures, generator 18 is transportable having a trailer 60 for movement on and off the service trailer 10, although it may be secured directly to the service trailer 10 without the trailer. More specifically, the generator 18 is a 25 KW GenSet having 120/240 volt single phase output and a “plug and play” power provision. The generator will provide power to the equipment on the trailer and to the environment of use, e.g. mobile restroom systems or mobile shower systems.

The light 20 provides light for a work area and/or for security. The light 20 pivots from a transport position as shown in FIG. 2 to a use position as shown in FIGS. 1 and 3 and includes a mast 54 and multiple lights 56, which in a preferred embodiment are metal halide lights preferably providing 440,000 lumens.

The fresh water tank water removal port 43 is connected by a water hose/pipe and connector 24 to a pump 22. It is understood the terms hose and pipe used herein are interchangeable and the hose/pipe may be flexible or inflexible. A preferred pump is a Utilitech 0.5 horsepower shallow well jet pump having cord 22A which is powered by generator 18. Pump 22 is connected by piping 25 to a pressurized accumulator tank with diaphragm 26 which tank is connected to a water outlet line 28 and the fresh water exits the service trailer through water outlet 30 by any suitable means such as a quick-lock connector and hose to connect to the end use facility, e.g. a mobile restroom system or a mobile shower system.

Service trailer 10 includes grey water tank 16 as discussed above. After the water is used, e.g. in a restroom facility or a shower facility, the grey water is removed from the facility to the service trailer by suitable hoses with quick-lock connectors at intake line 32 by an intake pump 34. The grey water is sent to a macerator 36 and the grey water is then removed by suitable hoses or piping 37 to grey water tank 16. The grey water is released through drainage port 41 by a suitable hose or piping 45 with a cut-off valve 45A to a grey water outlet 38. Preferably, a quick-lock connector and hose is connected to outlet 38 to remove the grey water to a sewage collection truck or tanker.

The service trailer 10 may be used to provide a self-contained, integrated Mobile Restroom System. The system stores fresh water, generates power, provides security lighting and manages grey water. The components of the service trailer 10 may be used independently, together or joined with other units to offer flexibility in a variety of deployment mission requirements. As an example, the Mobile Restroom System may generally comprise three components, namely, (1) a mobile restroom unit comprising six toilets (enclosed stall, with door), six faucets sinks and mirrors and 110 v AC electrical outlets (not shown); (2) a pressurized potable and grey water management system comprising a 750 gallon fresh water tank 14 and a 750 gallon grey water tank 16; (3) a power generator 18 with a portable light tower unit 20 comprising a 25 KW GenSet; a 120/240 volt single phase output; a plug and play power provision; light coverage covering 5 to 7 acres; and 440,000 lumens of light provided by metal halide lights.

The service trailer 10 may also be used to provide a self-contained, integrated Mobile Shower System. The system stores fresh water, generates power, provides security lighting and manages grey water. The components of the service trailer 10 may be used independently, together or joined with other units to offer flexibility in a variety of deployment mission requirements. As an example, the Mobile Shower System may generally comprise three components, namely, (1) a mobile shower unit comprising six shower heads, six faucets, sinks and mirrors and 110 v AC electrical outlets (not shown); (2) a pressurized potable and grey water management system comprising a 750 gallon fresh water tank 14 and a 750 gallon grey water tank 16; (3) a power generator 18 and a portable light tower unit 20 comprising a 25 KW GenSet; a 120/240 volt single phase output; a plug and play power provision; light coverage covering 5 to 7 acres; and 440,000 lumens of light provided by metal halide lights.

The service trailer 10 is, therefore, designed to incorporate all disciplines and equipment needed to operate multiple ablution modules and or units simultaneously without the need for added space requirements, multiple licensed personnel and associated logistics, unloading, and time consuming set-ups. The service trailer 10 is ready to operate upon arrival. Its “plug and play” layout provides for immediate service anywhere that power generation, potable water storage and distribution, waste water maceration and storage and removal, and security lighting are needed. The service trailer 10 is built to enable multiple services through one compact transportable unit.

Referring to FIG. 6, there is shown a plurality of the service trailers 10 in use to run a plurality of modular shower units and/or restroom units 60.
